Embodiment
Fig. 1-6 shows power forklift 10.As depicted in figs. 1 and 2, power forklift 10 includes driving crawler belt 15, is connected to
The framework 20 of (for example, rotation) driving crawler belt 15, and it is connected to the support arm 25 of framework 20.Support arm 25 includes lower end 30 (also referred to as
For support arm pin) and upper end 35 (also referred to as branch arm head).Power forklift 10 also includes the upper end for being rotatably installed in support arm 25
Pulley 40 on 35, the scraper bowl 50 for being connected to the spade 45 of framework 20, being connected to spade 45, the bale handle 55 for being connected to scraper bowl 50,
It is connected to the balancer 60 of bale handle 55 and is connected to the ropes 65 of framework 20 (for example, being connected to niggerhead).Lifting
Rope 65 is wrapped on pulley 40, and is connected to balancer 60.
When niggerhead rotates, ropes 65 are released to reduce scraper bowl 50, or are drawn into lift scraper bowl 50.Shovel
Handle 45 is slidably supported in saddle block 70, and saddle block 70 be pivotally mounted to framework 20 (for example, acknowledgement of consignment axle on,
It is not shown).Spade 45 is including rack structure 75 thereon, and it is engaged with the drive gear (not shown) in saddle block 70.
Drive gear is by electro-motor and excavates the driving of (crowd) gear unit (not shown), to extend or bounce back relative to saddle block 70
Spade 45.
Forklift 10 also include being connected to spade 45 and scraper bowl 50 both at least one leaning devices 80 (such as hydraulic cylinder,
Cylinder etc.).In shown structure, leaning device 80 is hydraulic cylinder.When activating in the first direction (Fig. 3), leaning device 80 prolongs
Stretch so that scraper bowl 50 tilts around pivotal point 85 (for example, pivotal pin), so that the tooth 90 of scraper bowl 50 rises.Pivotal point 85 is
Pivot section between spade 45 and scraper bowl 50.When activating in a second direction (Fig. 4), leaning device 80 bounces back so that scraper bowl
50 tilt around pivotal point 85, so that the tooth 90 of scraper bowl 50 reduces.Therefore, it can surround scraper bowl 50 by leaning device 80
Pivotal point 85 tilts, and can lift and reduce scraper bowl 50 by ropes 65.
One or more power supply (not shown) are also attached to framework 20, (are not shown with excavating motor to one or more
Go out) electric power is provided, gear unit is excavated to be used to drive, and power is provided to the niggerhead for being connected to framework 20.One or
Multiple hydraulic power source (not shown) are also coupled to framework 20, to provide power to one or more hydraulic tilt mechanisms 80, so as to
Drive the inclination of scraper bowl 50.Each in motor and hydraulic tilt mechanism 80 is excavated by one or more Motor Controls
Device drives, or is driven alternately in response to the control signal from controller (not shown).
As shown in figure 3, when activating leaning device 80 in the first direction, along with the rising of tooth 90, leaning device
80 reach fully extended position.In the position, as shown in figure 3, tension force F1 is combined with gravity F2 as caused by ropes 65,
F3 with joint efforts is generated on leaning device 80.When leaning device 80 starts to move in a second direction (that is, initially towards in Fig. 4
Fully retracted position movement, be commonly referred to as " rolling " in addition), power F3 is used as being applied to load on leaning device 80
Lotus.Such as when the powered direction of hydraulic cylinder is identical with the direction for being applied to load thereon, negative load will occur.Cause
This, when the hydraulic cylinder of leaning device 80 is driven by power supply by the left side generally into Fig. 3, power F3 makees in the same direction
With this can cause the negative load on hydraulic cylinder.If there is no enough Fluid pressures in leaning device 80 to resist the negative load,
Fluid cavitation (fluid cavitation) and/or runaway speed (runaway speed) may then be caused.Therefore, dumper
The hydraulic control of structure 80 provides back pressure (for example, constant back pressure), to control fluid cavitation.However, the back of the body is used in hydraulic cylinder
Pressure come prevent cavitation and/or it is out of control may reduce hydraulic efficiency, cause bigger energy expenditure, and/or reduce in hydraulic cylinder
Peak force.
As shown in figure 4, when activating leaning device 80 in a second direction, decline along with tooth 90 and approach but not
Ground is contacted, leaning device 80 reaches the position for being fully retracted or rolling.In this position, the tension force as caused by ropes 65
F4 is combined with gravity F2, and power F5 is generated on leaning device 80.When leaning device 80 starts to move along the first direction
(that is, the position movement for starting the full extension into Fig. 3), direction and the direction of motion phase of hydraulic cylinder due to power F5 effects
Together, power F5 plays a part of the negative load being applied on leaning device 80.Equally, if there is no enough stream in leaning device 80
Body pressure resists the negative load, then may cause fluid cavitation and/or runaway speed.
As shown in figure 5, when the excavation of ropes 65 and spade 45 keeps constant (that is, when drive gear and niggerhead
When not rotating), and scraper bowl 50 be inclined by via leaning device 80 (for example, starting material heap penetrate end after)
When, the slight uncontrolled motion of scraper bowl 50 can also occur.This sentences two kinds of situation explanations when ropes are directly connected to
The uncontrolled influence of scraper bowl is tilted during to the scraper bowl for allowing to pivot.Situation 1 occurs only hanging scraper bowl from ropes
Hang and when scraper bowl bottom is not placed on material heap.For example, as shown in figure 5, the inclination of scraper bowl 50 makes balancer 60
From first position, P1 is moved to second place P2.Therefore, for the angle of given spade 45, if banking motion extension is (i.e.,
Leaning device 80 extends towards fully extended position), then the excessive lifting that spade angle is given for this will be produced
Rope 65.If as there is no anything to be held in position in scraper bowl 50 in situation 1, with prolonging for banking motion
Stretch, spade 45 will be simply rotated down, and be pivoted around acknowledgement of consignment axle.This rotation will cause spade 45 toward whereabouts (for example, at certain
With as shown in Figure 5 about 8.6 ° in a little structures), this have impact on the operational control of scraper bowl 50, and reduce the whole of scraper bowl 50
Slant range (for example, the range shorter can use the 73% of slant range to whole) can be used.
In the (not shown) of situation 2, supported from below by material in P1 scraper bowl, and because it has been placed in material
On heap, ground or another material or object, so it will not fall.The inclination of scraper bowl 50 causes balancer 60 again from first
Position P1 is moved to second place P2.However, because scraper bowl can not drop downwards, so this movement is now in ropes 65
In generate relaxation (for example, in some structures, 2% relaxation that rope is released).Loose ropes are not conform to herein
Demand, because might have uncontrolled lifting suddenly now slings rope, this will cause scraper bowl bale handle 55 and balancer
60 unstable lifting control, so as to cause to produce the possible damage to ropes due to unexpected dynamic load.
Loose ropes can also make rope be come off in itself from pulley 40.
As shown in fig. 6, available tooth digging force (that is, cutting force) can also change according to the obliquity of scraper bowl 50.Example
Such as, as shown in fig. 6, when balancer 60 is in first position P1, the front portion of tension force F6 and tooth 90 in ropes 65
Between exist distance D1 (distance D1 from F6 extend vertically up to it is parallel with F6 and with the solid line of the front contact of tooth 90).Due to distance D1
Small, available tooth digging force DF1 is high.When scraper bowl 50 tilts and balancer 60 is in position P2, in tension force F6 and tooth 90
Between front portion exist distance D2 (distance D2 from F6 extend vertically up to it is parallel with F6 and with the dotted line of the front contact of tooth 90).Distance
D2 is noticeably greater than distance D1, and this causes when balancer is in position P2, and available tooth digging force DF2 is substantially reduced.If should
With new disclosed spade extension 295 (as described below), tooth digging force DF1 and DF2 will be increased.
As shown in Fig. 2 bale handle 55 and/or balancer 60 are also due to turning tooth load (the corner tooth of scraper bowl
Loading) and by bending load.Therefore, bale handle 55 and/or balancer 60 must be done sufficiently large, and by hard enough
Solid material be made, to bear the stress from these bending loads.In addition, scraper bowl 50 includes rear portion 95.The posterior
Divide 95 must be done sufficiently large, and be made up of sufficiently solid material, pivotal point 85 and another pivot farther out are passed through with processing
The high lifting bale handle power that load path between turning point 100 (bale handle 55 is connected to scraper bowl 50 herein) is applied.
Fig. 7-10 shows power forklift 210.Power forklift 210 is similar with above-mentioned power forklift 10.For example, forklift
210 include driving crawler belt 215, are connected to the framework 220 of (for example, rotation) driving crawler belt 215, and are connected to framework 220
Support arm 225.Support arm 225 includes lower end 230 (also referred to as support arm pin) and upper end 235 (also referred to as branch arm head).Power forklift 210 is also
Including be rotatably installed on the upper end 235 of support arm 225 pulley 240, be connected to the spade 245 of framework 220, be connected to
The scraper bowl 250 of spade 245, bale handle 255, the balancer 260 of bale handle 255 is connected to, and is connected to framework 220 (for example, connection
To niggerhead) ropes 265.Ropes 265 are wrapped on pulley 240, and are connected to balancer 260.
When niggerhead rotates, ropes 265 are released to reduce scraper bowl 250, or are drawn into lift scraper bowl
250.Spade 245 is slidably supported in saddle block 270, and saddle block 270 be pivotally mounted to framework 220 (for example,
Carry on axle, be not shown).Spade 245 is including rack structure 275 thereon, itself and the drive gear in saddle block 270
(not shown) engages.Drive gear is by electro-motor and excavates the driving of gear unit (not shown), to extend relative to saddle block 270
Or retraction spade 245.
Forklift 210 also includes being connected to spade 245 and scraper bowl 250 both at least one leaning devices 280 (such as hydraulic pressure
Cylinder, cylinder etc.).When activating in the first direction, leaning device 280 extends so that scraper bowl 250 surrounds pivotal point 285 (for example, pivot
Ship and resell on another market) tilt, so that the tooth 290 of scraper bowl 250 rises.Pivotal point 285 is that the pivot between spade 245 and scraper bowl 250 connects
Socket part.When activating in a second direction, leaning device 280 bounces back so that scraper bowl 250 tilts around pivotal point 285, so that shovel
The tooth 290 of bucket 250 reduces.Therefore, scraper bowl 250 can be made to be tilted around pivotal point 285 by leaning device 280, and can be with
Scraper bowl 250 is lifted and reduced by ropes 265.
One or more power supply (not shown) are also attached to framework 220, with to one or more motor (not shown)
Electric power is provided, excavates gear unit to be used to drive, and power is provided to the niggerhead for being connected to framework 220.One or more
Individual hydraulic power source (not shown) is also coupled to framework 220, to provide power to one or more hydraulic tilt mechanisms 280, so as to
Drive the inclination of scraper bowl 250.Each in motor and hydraulic tilt mechanism 280 is excavated by one or more motor controls

With continued reference to Fig. 7-10, bale handle 255 is not to be connected directly (for example, being pivotally connected to) to scraper bowl 250 (referring to example
Such as Fig. 1-6), but it is directly connected to spade 245.In shown structure, spade 245 is included at least the one of scraper bowl 250
The extension 295 (for example, end protuberance) extended on part.The remainder of extension 295 and spade 245 is integrally formed
Single part.Extension 295 extends at a certain angle relative to the remainder of spade 245, so that spade 245 is with non-
The profile of straight line.In other structures, extension 295 is the separation unit that (for example, fastening) is connected with the remainder of spade 245
Part.As shown in fig. 7, because bale handle 255 is directly connected to extension 295, so bale handle 255 is not directly contacted with scraper bowl 250, and
And it is spaced apart with scraper bowl 250.
As shown in figure 8, in shown structure, extension 295 includes the first arm 300 and the second arm 305.Arm 300 and 305
Bale handle 255 is pivotably connected at pivotal point 310 (one is shown in Fig. 8) place, this causes bale handle 255 to be arranged on two arms
Between 300 and 305, and pivoted relative to the remainder of two arms 300 and 305 and spade 245.
With continued reference to Fig. 8, two arms 300 and 305 are on the opposite side of the torque tube 315 of spade 245, and each other substantially
Extend parallel to.Although shown torque tube 315 is tubular structure, in other structures, torque tube 315 can have other
Shape and/or size.In other structures, two arms 300 and 305 are than shown closer to each other (for example, directly in torsion
The top of pipe 315 and/or neighbouring torque tube 315, cause smaller lighter bale handle 255 and/or balancer 260), or farther away from
Each other.In some structures, two arms 300 and 305 do not extend substantially in parallel each other.On the contrary, two arms 300 and 305
Define to form the axis of non-zero angle relative to each other.In some structures, on extension 295 only be provided with single arm or
Person is provided with more than two arm.In shown structure, arm 300 and 305 has slight crooked outline, and this causes the He of arm 300
305 upwardly extend and cross a part for scraper bowl 250.In other structures, arm 300 and 305 has straight profile, or is formed
A series of part of interconnection, each interconnecting parts are respectively provided with straight and/or bending profile.In some structures, extension 295
Including two arms 300 and 305, and one or more plates, post or the other structures of arm 300,305 are connected to, so as to be extension
Portion 295 provides further support.
As shown in Figure 9 and Figure 10, when (Fig. 9) in the first direction activates leaning device 280, leaning device 280 extend with
Scraper bowl 250 is set to be tilted around pivotal point 285, so that the tooth 290 of scraper bowl 250 raises.When (Figure 10) is activated in a second direction
When, leaning device 280 bounces back so that scraper bowl 250 tilts around pivotal point 285, so that the tooth 290 of scraper bowl 250 reduces.
When scraper bowl 250 fully extended (Fig. 9) and portion rebounds (Figure 10) two kinds of situations, extension 295 will not hinder or
Interfere significantly with the operation of scraper bowl 250.Any position and any position between them, scraper bowl 250 therefore can in both
It is inserted into material heap and removes material from material heap, and extension 295 will not significantly (or in some constructions, completely
Will not) interference scraper bowl 250 operation.As shown in figure 8, for example, scraper bowl 250 includes the opening 320 of adjacent teeth 290.The opening 320
Receive the material from material heap.In the construction illustrated, extension 295 slightly extends at least a portion of scraper bowl 250
Cross the opening 320 a part (such as so that the axis limited by ropes guiding piece 265 is extended through such as Fig. 7 and 7A
Shown opening), but the major part of still remaining opening 320 is open and exposes.
Therefore, in shown structure, extension 295 is made into extending at least partly on scraper bowl 250, but can not
Reach any degree significantly interfered with by opening 320 by material into and out scraper bowl 250.Meanwhile but extension 295
It is made into crossing scraper bowl 250 as much as possible and extends, (that is, is carried to provide the efficiency of maximum and the maximum amount of available tooth digging force
Beam is nearer from dipper teeth, and caused digging force is bigger).For example, as shown in figure 9, power F6 represents passing through from ropes 265
The power that bale handle 255 and balancer 260 are acted on scraper bowl 250.Power F7 is represented if bale handle 255 and balancer 260 are directly connected
The power acted on when being connected to scraper bowl 250 (as in figs. 1-6) on scraper bowl 250.As shown in figure 9, the distance between power F6 and tooth 290
D3 be less than the distance between power F7 and tooth 290 D4 (distance D3 and D4 be respectively perpendicular from F6 and F7 extend to it is parallel with F6 and F7 simultaneously
The dotted line contacted with tooth 290).Because distance D3 is less than D4, so by the way that bale handle 255 is directly connected into energy on extension 295
It is enough that there is bigger mechanical efficiency and available tooth digging force.In some structures, the difference between distance D3 and D4 is about 30
Between inch and 37 inches.In some structures, the difference between distance D3 and D4 is between about 25 inches and 42 inches.It is other
Structure includes different value and scope.
Similarly, as shown in Figure 10, power F8 represents to act on by bale handle 255 and balancer 260 from ropes 265
Power on scraper bowl 250.Power F9 is represented if (such as in Fig. 1-6 when bale handle 255 and balancer 260 are directly connected to scraper bowl 250
In) power that acts on scraper bowl 250.As shown in Figure 10, the distance between power F8 and tooth 290 D5 are less than between power F9 and tooth 290
Distance D6 (distance D5 and D6 is respectively perpendicular from F8 and F9 extends to dotted line that is parallel with F8 and F9 and being contacted with tooth 290).By
Be less than D6 in distance D5, thus by by bale handle 255 be directly connected on extension 295 can have bigger mechanical efficiency and
Available tooth digging force.Therefore, no matter scraper bowl 250 be located at fully extended position (Fig. 9), portion rebounds position (Figure 10) or
Other any positions of person, can have bigger mechanical efficiency and available tooth digging force.In some structures, distance D5 and
Difference between D6 is between about 10 inches and 14 inches.In some structures, the difference between distance D5 and D6 is at about 8 inches
And between 16 inches.Distance D5 and D6 can also be influenceed by rope angle, and it can be formed by excavating extension and spade angle
Function.Therefore, distance D5 and D6 may change, and simultaneously non-individual is determined by angle of inclination.Other structures include difference
Value and scope.
The advantages of many extra is additionally provided using extension 295 and the bale handle 255 for being directly connected to extension 295.Example
Such as, because compared with scraper bowl 55, the General load and stress on scraper bowl 255 are smaller, it is possible to make scraper bowl 250 lighter, so as to
It is cheaper than above-mentioned scraper bowl 55.Therefore, scraper bowl 255 can use less plate and/or welding.
In addition, the negative load (that is, power F3) shown in Fig. 3 is greatly reduced on power forklift 10.Gravity F2 will be carried
For some negative loads, but due to ropes 265 hold spade 245 (that is, by bale handle 255 and balancer 260) rather than
Hold behind scraper bowl 255, so tension force F1 will be eliminated.Due to remove shown in tension force F4, Fig. 4 on leaning device
Negative load eliminated completely from power forklift 210, on condition that the power provided without outside, such as tooth forces from material heap
Material (for example, gravity of scraper bowl) in (when excavating) or scraper bowl.In a word, the thing that negative load reduces in seriousness and frequency
The real use for causing above-mentioned high hydraulic backpressure is by significant reduction.This ability for reducing back pressure provides more efficient hydraulic operation
System, because it reduces to prevent cavitation and the amount of constant backpressure that is out of control and must applying in hydraulic cylinder.With drop
Low backpressure requirements, leaning device 280 can have increased surge pressure.In some structures, because the back pressure of reduction will
Ask, the size of leaning device 280 can be additionally or alternatively reduced, thus cost-effective.However, in either type,
Because back pressure is used as the resistance (drag) of hydraulic fluid transmission, and by using the bale handle for being directly connected to extension 295
255 and reduce the resistance, therefore energy efficiency increase.
With continued reference to Fig. 7-10, as described above, the turning tooth on scraper bowl that will inevitably occur during excavation
Load, have around bale handle connects and enters the load path of spade 245.Therefore, because bale handle 255 and balancer 260 and shovel
The isolation of bucket 250, so the influence of the turning tooth load in bale handle connection can be lowered on power forklift 210 or disappear completely
Remove.Therefore, compared with bale handle 55 and/or balancer 60, bale handle 255 and/or balancer 260 can be with less materials and weight
Manufactured, this provides extra cost savings.In addition, eliminate allows scraper bowl 255 to compare scraper bowl by the bale handle load path of scraper bowl
55 have less full payload and stress, so as to save extra weight and cost in scraper bowl 255.
Further, since when drive gear and niggerhead do not rotate and scraper bowl 250 tilts, spade 245 (and then bale handle
255 and balancer 260) will not move, can be completely eliminated so spade shown in Fig. 5 falls.On the contrary, only scraper bowl 250
Itself is mobile.Therefore, because scraper bowl 250 is isolated from bale handle 255 and balancer 260, and because bale handle rope 265 is directly connected
Balancer 260 is connected to, so bale handle rope 265 is not influenceed by the banking motion of scraper bowl 250, and line relaxation will not occur
Also spade whereabouts will not occur, regardless of whether scraper bowl is supported by ground.
As shown in Figure 7 A, forklift 210 also includes spade pivotal point 325, and spade 245, which encloses, to be pivoted about.In some structures,
Spade pivotal point 325 is defined as a point or region, and on the point or region, spade rack is (for example, similar to shown in Fig. 1
Rack structure 75) be tangentially shelved on acknowledgement of consignment shaft gear on.
As shown in Figure 7 A, the lifting bale handle acted on along ropes 265 draws vector F 10 at the tip 330 of dipper teeth
Place produces digging force vector F 11.The direction of digging force vector F 11 and between spade pivotal point 325 and the tip 330 of dipper teeth
The dotted line directly extended is at right angles (digging force vector F 11 corresponds to tooth digging force DF1 and DF2 for example as shown in Figure 6).Such as figure
Shown in 7A, the arc 335 of the also dipper teeth with being rotated around spade pivotal point 325 of digging force vector F 11 is tangent.Producing these arrows
In some constructions of amount, active force and the active force of bucket tilt that spade excavates are not active, but are passively resisted
Reaction force.If they produce extra power and motion on one's own initiative, then in this illustration, it can influence the point in dipper teeth
Hold amplitude and the direction of the caused digging force vector F 11 limited at 330.
With continued reference to Fig. 7 A, the vertically measurement distance D7 between two parallel dotted lines, wherein first dotted line passes through
Spade pivotal point 325, Article 2 dotted line extend along lifting bale handle traction vector F 10.Vector F 10 is being drawn along lifting bale handle
The dotted line of extension and extend through dipper teeth tip 330 parallel dotted lines between vertically measurement distance D8.Distance D9 is determined
Justice is the direct range between the excavation force vector at spade pivotal point 325 and the tip 330 for acting on dipper teeth.
With continued reference to Fig. 7 A, equalising torque be present on forklift 210 so that lifting bale handle force vector F10 be multiplied by away from
Size from D7 is equal to the size that digging force vector F 11 is multiplied by distance D9.Digging force vector F 11 is bigger, and scraper bowl 250 excavates material
The ability of heap is better.Therefore, do not increasing from the effect needed for any motive power (for example, excavating motor) on forklift 210
In the case of power and energy, the Geometrical change of any increase digging force vector F 11 can be such that forklift 210 and scraper bowl 250 more has
Efficiency.
With continued reference to Fig. 7 A, lifting bale handle traction vector F 10 is bigger, is excavated obtained by the tip 330 of dipper teeth
Force vector F11 is bigger.With lifting bale handle traction vector F 10 move close to dipper teeth tip 330 (and away from spade pivot
325), the amplitude of resulting digging force vector F 11 increases point, active force and energy without increasing motive power.Namely
Say, as D7 becomes big and D8 diminishes, the digging force vector F 11 obtained at scraper bowl tip 330 increases, and excavation becomes more efficient.
As shown in Figures 9 and 10, the spade angle in each figure is in about 30 ° with horizontal direction, and this corresponds to when operation
Member complete initial insertion to material heap and will tilt at once and from material heap upgrade the material of full scraper bowl when typical case
Spade angle.Excavate the cycle on this point, scraper bowl that operator may need sufficient active force will be filled with is from thing
Pulled out in material heap.In some structures, thus, the spades of 30 ° of full extensions is available at the tip 330 to dipper teeth
The place that digging force vector F 11 optimizes.
Figure 11-15 shows forklift 410.Forklift 410 is similar to above-mentioned forklift 210.Therefore, similar part is with identical
Numeral is referenced plus 200.However, forklift 410 does not include the hydraulic tilt mechanism for its scraper bowl 450.On the contrary, scraper bowl
450 are rigidly secured to spade 445 along spade 445 at tie point 452.In this configuration, the extension of spade 445
495 are connected to the torque tube 515 (for example, being directly connected to or be integrally formed into single part by welding) of spade 445, and
Bale handle 455 is connected to extension 495 (that is, two arms 500 and 505 for being connected to extension 495 as shown in figure 12), so as to
So that bale handle 455 is isolated with scraper bowl 450.As shown in figure 12, spade 445 is in itself non-directional, and curved at position 446
It is bent.In some structures, the non-rectilinear spade 445 of bending adds for rigidly connected scraper bowl 450 and rolls ability peace floor
Cleanup area.In addition, as shown in figure 12, the first arm 500 of extension 495 and the second arm 550 each directly prolong from torque tube 515
Stretch.
Figure 13 and 14 shows along the flange of scraper bowl 450 the centre tooth load as caused by digging force F12 at centre tooth
Path (power F13 represents the power applied by ropes).As shown in figure 14, in position 411 (for example, in the base portion of extension 495
Place) heavy bent/twisted may occur.Torque tube 515 can play an important role in terms of resistance bending moment and shear-type load.
The bending at the rear portion of bale handle 455 and scraper bowl 450 may be minimized at position 412.As shown in figure 14, one in position 412
Individual is the rear portion of scraper bowl 450, and another in position 412 is interface between bale handle 455 and extension 495 (for example, shearing
With the bale handle pin under bending load, and because bale handle 455 no longer reaches opposite side from the side of scraper bowl 450, so it bends
Load is minimized).Torsion can be passed through at position 413 by centre tooth load path (dotted line) caused by digging force F12
Pipe 515 is driven.Torque tube 515 can be absorbed due to the centre tooth load path and caused most of bending and torsion.
In some structures, the quality of torque tube 515 can be increased, in order to absorb these load.Due to torque tube 515 resistance these
The heavy in section performance of load, torque tube 515 are more beneficial for absorbing heavier load.
Figure 15 shows the turning tooth load F14 of scraper bowl 450, and the caused reaction force on the part of forklift 510
F15.As shown in figure 15, the load transfer path (dotted line) from load F14 is along generally U-shaped direction, so as to cause direction
Two change.Torque tube 515 absorbs a large amount of bending moments as caused by load F14.
Figure 16-19 shows forklift 610.Forklift 610 is similar to above-mentioned forklift 210.Therefore, similar part is with identical
Numeral is referenced plus 400.Similar with forklift 410, forklift 610 does not include the hydraulic tilt mechanism for its scraper bowl 650.Phase
Instead, scraper bowl 650 is rigidly secured to spade 645 along spade 645 and extension 695 at tie point 652.Such as Figure 16 institutes
Show, bale handle 655 is connected (for example, being directly connected to) between the end of extension 695 and arm 700 and 705 in extension 695
To extension 695, so that bale handle 655 is isolated with scraper bowl 650.
Figure 17 and 18 shows along the flange of scraper bowl 650 the centre tooth load as caused by digging force F16 at centre tooth
Path (power F17 represents the power applied by ropes).As shown in figure 18, in position 611 (for example, in bale handle 655 and extension
695) bending of weight may occur.Because bale handle 655 and extension 695 bear bending moment and shear-type load, after scraper bowl 650
The bending in portion can be minimized at position 612.In some structures, the bending in torque tube 715 can also be minimized.
Centre tooth load path (dotted line) can be driven through spade 645 and enter bale handle 655.Bale handle 655 and extension 695 can be with
Absorb caused most of bending due to the centre tooth Load Path.
Figure 19 shows the turning tooth load F18 of scraper bowl 650, and the caused reaction force on the part of forklift 610
F19.As shown in figure 19, the load transfer path (dotted line) from load F17 is along all directions, so as to cause the four of direction
Change.Spade extension 695 and bale handle 655 absorb the substantial amounts of moment of flexure as caused by load F17.As shown in Figure 15 and Figure 19, figure
Load transfer path in 19 structure remote as in Figure 15 structure will not extend back (from shown in direction 651 to
Rear to).Therefore, in Figure 19 structure, bale handle 655 and extension 695 can be made into it is heavier or stronger, and Figure 15's
In structure, torque tube 515 can be made into heavier or stronger.As in figs. 17-19, its load path generally than be used for Figure 13-
The load path of 15 structure is more roundabout.
As shown in figs. 11-19, extension 495 and 695 is completely directly taken over the bang path for lifting vector part to shovel
In handle 445 and 545, rather than pass through scraper bowl 450 and 650.Therefore, spade 450 and 650 does not suffer from the load from ropes
Lotus.On the contrary, ropes direct pull spade 445 and 645, so that spade 445 and 645 is subjected to the load from ropes
Lotus.In some structures, this arrangement allows to form spade 450 and 650 with less the form of quality and lower cost, because
Spade 450 and 650 no longer Structure of need supports the load from ropes.In some structures, it is this arrangement allow by
Increased architecture quality from the rear portion of scraper bowl 450 and 650 (that is, herein architecture quality be previously used for support come from hoisting rope
The load of rope) it is displaced to such as bottom of torque tube (for example, torque tube 515) and spade extension (such as extension 495).No
The structure of more weight is same as behind scraper bowl 450 and 650, but heavier structure is further placed backward, because these areas
Load will be driven rearward in domain.Between Figure 11-15 and Figure 16-19 two kinds of structures, Figure 11-15 structure is more backward
Quality is driven, because bale handle is attached to torque tube.Rearward displacement in Figure 11-19 allows the tip (example in scraper bowl flange
Such as, on tooth) bigger digging force is formed, and/or equilibrant force on forklift is reduced (because bigger weight is closer to forklift
Center line), and/or swing inertia less possessed by forklift during swing, this also brings response and starts faster/stop
Only.
In addition, as described above, when using Figure 11-15 construction, turning tooth load shifts load transfer path enough onto
Remote position, so that torque tube 515 absorbs substantial amounts of load.Torque tube 515 can be formed with increased quality
For absorbing load, and bale handle 655 and scraper bowl 650 can be made to be done lighter (for example, being carried by using what width reduced
Beam 655, or overall less bale handle 655 or scraper bowl 650).In some structures, the structure (example of scraper bowl 650 itself can be reduced
Such as, all-box-shape section is reduced, so as to be advantageous to open gusset structures (gusset structure)).In some structures
In, scraper bowl 450 and 650 is the Fast Wearing article being often replaced.Structure is lighter, and cost is lower.
Although the present invention is described in detail by reference to some preferred embodiments, in described of the invention one
Or exist in the scope and spirit of multiple independent aspects and change and modifications.
